[for-next][PATCH 1/3] tracing: Remove redundant check on field->field in histograms

[Steven Rostedt <rostedt@goodmis.org>]

From: Colin Ian King <colin.i.king@gmail.com>

The check on field->field being true is handled as the first check
on the cascaded if statement, so the later checks on field->field
are redundant because this clause has already been handled. Since
this later check is redundant, just remove it.
